Description

The present invention relates to a folding sealed letter creating apparatus capable of delivering a large amount of information to individuals as a sealed mail type direct mail or the like.

As a method for delivering a large amount of information to individuals, there is a method in which a booklet-like printed matter is enclosed in an envelope and shipped. In this case, the envelope and the booklet-like printed matter have to be printed and processed separately, which requires a lot of man-hours and labor.

In order to solve this problem, there have been proposed envelopes created by a collation method and a zigzag folding method in which envelopes and contents are glued and folded after printing to produce an envelope-shaped DM.

A sealed letter created by the collation method has a plurality of sheet-shaped sheets of paper that have been printed on a single cover with a larger folding width. After aligning and stacking, the cover side protruding from the contents paper is used as the glue margin, and after applying glue to each glue margin, the fold at the center in the width direction becomes a valley, that is, the cover is folded out The adhesive margin parallel to the crease is pasted on the back side of the cover, and the margin margin perpendicular to the crease is adhered to each other to make a sealed letter sealed around the contents.

The sealed letter created by the zigzag folding method is a continuous form in a zigzag form with a set of a plurality of contents paper that is between the front and back cover parts and both cover sheets and halved the cover width. It is folded in the form. Then, it is folded and the extension part of each cover is wound on the opposite side and heated and pressed, so that it is integrated with the thermoplastic glue previously applied to the marginal zone and the front end part of the cover part, and the folding sealed letter It is supposed to be.

This is shown in the prior art of Japanese Patent Application No. 2002-228750.

Among the conventional techniques described above, in the collation method, multiple contents and one cover must be printed and processed in separate processes, and collated with a collator, etc. There was a problem in terms of cost.

Also, in the zigzag folding method, the front and back cover extensions are wound on the opposite sides and heated and pressed, so it is necessary to go through complicated steps in producing the production device in that method, equipment, cost There was a problem in terms. The present invention has been made in view of the above,
It is an object of the present invention to provide an apparatus for continuously producing a folding envelope from a continuous form with a reduced number of man-hours and equipment, and therefore at a low cost.

In order to achieve the above object, the folding envelope according to the present invention is folded in a zigzag shape, with the origami located at both ends as covers, the folding width of both covers being wider than the folding width of the contents paper, Projecting in the folding width direction from the contents paper, and the folding width of the contents paper connected to each cover is made wider according to the folding width of the cover, and the projecting parts and each cover in the folding width direction from the contents paper of each cover The part which opposes each of the part which protrudes in the folding width direction of the content paper of the part connected to is comprised.

The folding envelope is created by a variable transverse sewing machine that is driven by a sectional motor and can process transverse perforations at random intervals in the running direction of the continuous foam, and is driven by the sectional motor and processed by the variable transverse sewing machine. A variable folding machine having a folding device that folds a continuous foam with a folding width formed by a horizontal perforation, and in the variable folding machine, the continuous foam is united along each horizontal perforation processed by the variable horizontal perforation.

Thus, a pressure bonding device for bonding is provided.

In a variable horizontal sewing machine, a sectional motor operates in accordance with a command from the control device, and a continuous form running at a predetermined speed has a horizontal sewing machine with a random pitch so that the folding widths of the front and back covers and the contents paper are different. Eyes are put in. In the variable folding machine, a sectional motor that drives the variable horizontal sewing machine is controlled in synchronization with the operation of the variable horizontal sewing machine, and the continuous form is folded along the horizontal perforations randomly inserted by the variable horizontal sewing machine.

After that, the continuous foam that is randomly folded is cut for each set by the cutting device, then folded by the variable folding machine, and discharged by the set unloading device one set at a time.
Then, it is pressure-bonded by a pressure bonding apparatus, and is bonded and sealed with a pressure-sensitive adhesive or a heat-sensitive adhesive that has been applied in advance.

According to the sealed letter making apparatus of the first aspect of the present invention, the front and back cover sheets can be directly bonded with glue, and the sealed letter can be continuously printed from a continuous form with less man-hours and equipment, and therefore at low cost. In addition to being able to create, it is not necessary to carry and transport between processes, which are necessary when creating in a plurality of processes.

The nozzle roller 36 is supported by the swinging shooter 33 through a bearing box 37 rotatably supported by the swinging shooter 33, and the center of rotation of the bearing box 37 with respect to the swinging shooter 33 is supported. 02 is slightly eccentric with respect to the center of the bearing housed in the bearing housing 37, that is, the rotational center 03 of the nozzle roller 36, for example, about 1 mm.

The bearing box 37 is provided with an arm 38, and an operating cylinder 39 of the cutting device 31 is connected to the arm 38. By extending and contracting the operating cylinder 39, the bearing box 37 is rotated, and the nozzle roller 36 can be moved in a direction in which the receiving roller 35 is brought into contact with and separated from the eccentric amount δ1. That is, when the operation cylinder 39 is shortened, the nozzle roller 36 is separated from the receiving roller 35 by a small dimension, for example, a dimension smaller than the thickness of the continuous foam 1 (first position), and the expansion operation is performed. In some cases, the nozzle roller 36 is in a state of being strongly in contact with the receiving roller 34 (second position).

A driven pulley 40 is fixed to one end of the nozzle roller 36, and this driven pulley 40 is connected to a driving pulley 41 provided coaxially with the rotation fulcrum 0 of the swinging shooter 33 by a belt. The driving pulley 41 is connected to a power shaft of a folding device by a connecting device (not shown), and the rotation of the driving pulley 41 causes the peripheral speed of the nozzle roller 36 to be higher than the traveling speed of the continuous foam 1. In this way, it is driven to rotate. The receiving roller 35 and the nozzle roller 36 are connected by a gear so that the rollers 35 and 36 rotate in the running direction of the continuous foam 1 and at the same peripheral speed. Although the meshing state of the two gears changes due to the eccentric operation of the nozzle roller 36, this change is extremely small and causes no particular problem.

On both sides of the swinging shooter 33, a pair of blades 43, 43 driven by a folding screw drive device 42 and screws 44, 44 are provided. The continuous form 1 which operates synchronously and is sent out from the swinging shooter 33 is folded, and these configurations are the same as the conventional ones. 45 is a conveyor.

The upstream side of the swinging shooter 33 is a paper cutting path 47 that is vertically formed from the swinging shooter 33 to the pull roller 46, and the impression cylinder that faces this sheet cutting path 47 across the sheet cutting path 47. A cut drum device 50 including 48 and a cut drum 49 is disposed. The cut drum device 50 is configured as shown in FIGS. 6 and 7. The pressure drum 48 and the cut drum 49 are respectively attached to the front and rear frames 53 via bearing boxes 51 and 52 having bearings therein. It is supported rotatably. The two cylinders 48 and 49 have the same diameter as an example, and gears 54 and 55 fixed to each of them are meshed. A pulley 56 is fixed to the impression cylinder 48.

It rotates with 71.

The bearing box 51 of the impression cylinder 48 is fixed to the frame 53, but the bearing box 52 of the cut cylinder 49 is supported rotatably with respect to the frame 53. The rotation center O4 of the bearing box 52 with respect to the frame 53 is eccentric with respect to the rotation center O5 of the cut drum 49 by δ2. A segment gear 57 having the center of rotation O4 of the bearing box 52 as an axis is fixed to the bearing box 52 of the cut drum 49, and fixed to a shaft 59 that is rotatably supported by the frame 53 on the segment gear 57. The actuated gear 58 is meshed. And this operating gear 58
An operating cylinder 61 is connected to an arm 60 fixed to the shaft 59.

The operation cylinder 61 expands and contracts to rotate the arm 60, whereby the gear box 52 is eccentrically rotated with respect to the rotation center O5 of the cut drum 49 via the operation gear 58 and the segment gear 57, The cut cylinder 49 is moved toward and away from the impression cylinder 48. At this time, the distance between the shafts of the impression cylinder 48 and the cut cylinder 49 changes, but since the length thereof is slight, the meshing of the gears 54 and 55 meshing with each other is meshed without any difficulty in rotation.

Further, the cut cylinder 49 is pivotally supported on a frame different from the impression cylinder so that the cut cylinder can be replaced with a cut cylinder of a size that can be cut at that size, and the cut cylinder is screwed or fixed together with the frame. The gear 55 fixed with the jig and fixed to the cut cylinder 49 is the gear 54 of the impression cylinder 48.
In some cases, a structure capable of cutting various sizes by being engaged with each other is provided, or the gear 55 of the cut cylinder 49 is removed to eliminate the engagement with the gear 54 of the impression cylinder, and a single motor (not shown). The cutting cylinder 49 of fixed size is driven and controlled, and the cutting cylinder 49 is shifted every rotation, and the circumferential speed is adjusted to the running speed V1 of the continuous form 1 only when the cutting blade 62 enters, and the continuous form is formed at the designated position. 1 can be cut off.

A full blade type cutting blade 62 having a length extending over the entire length of the cutting body 49 is fitted and fixed in a groove 63 provided over the entire length of the cutting body 49. This cutting blade 62
Is protruded from the cut cylinder 49 by a gap S between the impression cylinder 48 and the cut cylinder 49. This cutting blade 62 is configured as shown in FIG. 8, and a blade 62a is provided over the entire length thereof.
Cutouts 65 are provided at a plurality of places, for example, two places over the entire length. This notch 6
The depth of 5 is deeper than the projecting length S from the cut body 49. A groove 66 is provided on the circumference of the cut body 49 at a position corresponding to the notch 65 of the cut blade 62.

In the vertical paper cutting path 47 in the 50 parts of the cutting cylinder device, this paper cutting path 4
A sheet guide device 67 for guiding the continuous form 1 passing through 7 is provided. This paper guide device 6
7 is composed of two guide wires 68a and 68b facing each other across the paper cutting path 47, and these guide wires 68a and 68b are provided on each of the cutting blades 62 as shown in FIGS. It arrange | positions in the notch 65 part.

An upstream side of the paper cutting system path 47 is a paper guide system path 73 in which pull rollers 46 and 71, a compensation roller 72, a guide roller, and the like are arranged, and the pull roller 46 and the compensation roller 72 of the paper guide system path 73 are arranged. A mark sensor 74 is provided at a position facing the guide roller between them.

The operation of the cutting device 31 and the folding device 32 will be described. The continuous form 1 is pre-marked at the time of printing on the horizontal perforations 4 between the front cover 2a and the back cover 2b, which are cut portions, and is drawn by the pull rollers 46 and 71. The continuous form 1 passes through the pull roller 71, the compensating roller 72, the pull roller 46, and a plurality of guide rollers to the paper cutting path 47, and swings in a zigzag manner from the nozzle roller 36 according to the swinging of the swinging shooter 33. Then, the creases are pressed by the blades 43 and 43 and the screws 44 and 44 and are folded and stacked on the conveyor 45.

At this time, the compensator 72 adjusts the span in the paper cutting path 47 of the continuous form 1 to align the position of the cutting blade 62 of the cutting cylinder 49 with respect to the horizontal perforation. At this time, both the cylinders 48 and 49 of the cutting cylinder device 50 of the cutting device 31 are rotated at substantially the same speed as the traveling speed of the continuous foam 1. In normal cases, the operating cylinder 61 of this cutting cylinder device 50 is used. Is shortened to keep the cut drum 49 in an eccentric position.

As a result, the cut cylinder 49 moves in the direction away from the impression cylinder 48 around the eccentric center O4, and the cut blade 62 also moves obliquely downward in FIG. . Further, the continuous form 1 passing through the paper cutting path 47 is formed by a cutting cylinder device 50.
It is guided by passing between the wires 68a and 68b of the guide device 67 provided between the two cylinders 48 and 49.

At this time, the nozzle roller 36 is moved by the shortening movement of the operating cylinder 39 to receive the roller 3.
It is eccentrically positioned in a direction away from 5, and is rotated away from the receiving roller 35 so that the continuous form 1 is lightly pressed.

Accordingly, at this time, the continuous foam 1 at the nozzle roller portion is swung out in a state where the nozzle roller 36 rotates slightly faster than the running speed of the continuous foam 1 and is slightly pulled out while sliding at this portion. The slack caused by the swinging motion is the nozzle roller 36.
Absorbed in

In the above state, when the mark marked on the continuous form 1 is detected by the mark sensor 74, the operation cylinder 61 of the cutting cylinder device 50 is extended in response to the signal, and a predetermined lateral perforation is cut. When the cylinder device 50 is reached, the cut cylinder 4
9 is decentered in the direction approaching the impression cylinder 48 side, and the cutting blade 62 comes into contact with the horizontal perforation, whereby a cut is made in the horizontal perforation. When the cut drum 49 is driven by a single motor, the above-mentioned separation / contact operation is not performed, the cut blade 62 is held at a position where it can abut on the horizontal perforation, and the horizontal perforation with a mark is predetermined. When the position is reached, the peripheral speed of the cut drum 49 is adjusted to the traveling speed V1 of the continuous foam 1, and the continuous foam 1 is cut at a predetermined position.

As shown in FIG. 8, a portion corresponding to the notch 65 of the cutting blade 62 is left as a joint 77 for the cutting 76 by the cutting blade 62 as shown in FIG. After the operation, the cut cylinder 49 is eccentrically moved in the direction away from the impression cylinder 48 immediately by the operation of the operation cylinder 61 in the reverse direction.

The cut portion 76 passes through the guide roller and enters the swing shooter 33 as it is.
The working cylinder 39 of the nozzle roller 36 extends and is pressed against the roller 35 side at the timing when the cut 76 comes immediately before the nozzle roller 36.

As a result, the downstream side of the cut portion 76 of the continuous form 1 is pulled by the nozzle roller 35 rotating faster than the running speed of the continuous form 1, and the joint 77 of the cut portion 76 is torn. It is cut at the cut 76 part. After the above operation, the operation cylinder 39 immediately operates in the reverse direction, and the nozzle roller 36 is eccentrically operated in a direction to release the pressure on the receiving roller 34. Accordingly, the leading edge of the continuous sheet 1 after being cut is directly swung out from the nozzle roller 36.

On the other hand, the cut portion is immediately separated from the nozzle roller 36 by the blade 43 and the screw 4.
